BOSCH 18SG-5E Review

The BOSCH 18SG-5E is a high-quality concrete surfacing attachment that is compatible with small angle grinders in the AG, GWS, and 1800 series with a 4-1/2 inch or 5 inch wheel size (excluding GWS8-45, GWS9-45, and GWS18V-45). It is completely tool-free, making it quick and easy to install and remove, and features a removable nose piece for flush surfacing. In addition, the attachment includes a replaceable brush ring for low-cost maintenance compared to the competition.

One of the most notable features of the BOSCH 18SG-5E is its dust collection system. The attachment is designed to reduce clean-up time and provide cleaner, safer air for the user. The included dust extractor is well-balanced and collects dust effectively when paired with the correct wheel. However, some users have noted that the dust extractor is shallow compared to aftermarket and other brand versions, which can lead to dust problems if the wheel extends beyond the bristle shroud.

Despite this issue, the BOSCH 18SG-5E has received overwhelmingly positive reviews from users. It is praised for its efficiency, ease of use, and ability to reduce cleanup time. Many users have reported that it plows through thinset and other materials quickly, with minimal dust outside of the shroud when connected to a shop vac. The attachment holds the grinder cup at just the right height for quick, level cuts that don't damage the subfloor.
